Reptiles are a diverse group of cold-blooded vertebrates belonging to the class Reptilia. They are characterized by several distinct features that differentiate them from other animal groups.<div>
</div><div>Scale-covered skin: Reptiles have dry, scaly skin that helps them conserve water and protect against desiccation. The scales are made of keratin, the same material found in human hair and nails.</div><div>
</div><div>Ectothermic metabolism: Reptiles are ectothermic, meaning they rely on external sources of heat to regulate their body temperature. Unlike warm-blooded mammals and birds, reptiles do not generate their own internal heat.</div><div>
</div><div>Terrestrial adaptation: While some reptiles can live in aquatic environments, the majority are adapted to terrestrial life. They have well-developed limbs or, in some cases, are limbless (e.g., snakes). This allows them to move effectively on land.</div><div>
</div><div>Respiratory system: Reptiles breathe using lungs. They have a more efficient respiratory system compared to amphibians, allowing them to extract more oxygen from the air.</div><div>
</div><div>Reproduction and development: Most reptiles lay amniotic eggs, enclosed in a protective shell that prevents desiccation. This adaptation frees them from the need for an aquatic environment for reproduction, unlike amphibians. However, some reptiles give live birth, including certain species of snakes and lizards.</div><div>
</div><div>Reptiles encompass several different groups, including turtles, snakes, lizards, crocodilians (such as crocodiles and alligators), and tuatara (a reptile found in New Zealand). They inhabit a wide range of habitats across the globe, from deserts to forests, and play important roles in ecosystems as predators, prey, and ecosystem engineers.</div><div>
</div><div>Reptiles have been around for millions of years and have evolved numerous adaptations that have allowed them to thrive in diverse environments. They are an ancient and fascinating group of animals that have adapted to survive in various ecological niches.</div>
